Hi guys,Long time I did not post a problem ^^I changed my config to a new one: I7-860 / ATI5870 / 8 Gigs and Win7-64 Pro. So I decided to take my FSX from the dusty shelve. The start was hard, with multiple problems (the automation file thing from Vista helped me in stoping CTD.)But now that I just started to enjoy it, FSX gave me a new one: it now stops after 30 min, saying that it is a trial version. Riiiiiight, made some middle haul without problems some days ago . The problem is that I can't see anywhere where to put again my serial number ! I promise I searched lol.Don't know where this comes from, so one more time, your precious help is more than apreciated !Regards,Emmanuel.

One more thing I did not mention: all my hard drives are new too. C:\ for OS and D:\ for the rest (incl. FSX)Dunno if it will helps.Emmanuel.

No one for an idea ?Thanks,Emmanuel

If all else fails, there should be an 800 number to call MS. They should be able to reactivate it for you. Maybe try to uninstall, and reinstall it?

Hi all,Just to let you know that the flight1 registry fix made it, registration status was back to normal after patch.Thanks for your help !
